Tissues And Hormones Of The Endocrine System

Lab Exercise – Tissues and Hormones of the Endocrine System Your name Your Institution of Affiliation April 1, 2018 Introduction The Endocrine system is one of the most essential parts of the body. Its functions encompass almost every aspects of our body’s functioning and regulation – from sleeping, metabolism, mood regulation, and reproduction amongst others CITATION Zim18 \l 1033 (Zimmermann, 2018). Structurally, this whole system consists of eight (8) major glands together with the pancreas that functions for hormone secretion and digestion, respectively CITATION Kem17 \l 1033 (Kemp, 2017). Hormone secretion is crucial for the body as these chemicals could either act as an inhibitor or stimulator, through process of feedbacks that then maintains the body’s homeostasis. In this lab experiment, the researchers conducted a more in-depth study about the structure and function of the system. Particularly speaking, the focus would be on the different cells that makes all of these processes possible. Its structures, functions and the specific regulatory mechanisms would be examined in further detail and compared to one another. In the succeeding section of this study, a focus on the origins on both tropic and non-tropic hormones, their target tissues, and its effects would also described. Although, it would only be the structure that would be focused with the staining process of the experiment. All in all, the researchers believed that by knowing the very structures of these cells, it would be easier to understand the very processes that are ongoing and keeping us alive. Material List: No materials are required for this experiment Methods: The experiment starts with procuring a microscope and the samples of different endocrine cells. After securing these a well-lit spot was found in order to provide a better magnification of the samples. Throughout the whole process, the order in which the samples were studied was from low, to medium, and to the highest magnification in order to provide a clearer view of the whole structure. All of them were also labeled based on the structures found. The order and the specific structures of each sample that was examined is given below. 1 Pituitary Gland – Anterior; acidophil cells and basophil cells. Posterior; Nucleus of the Pituicyte. 2 Thyroid gland – Follicular Epithelial cells and Colloid 3 Adrenal Gland – capsule, zona glomerulosa, medulla, zona reticularis, zona fasciculate 4 Pancreas – Islet and Acinar Cells 5 Ovary – Follicles 6 Testes – spermatogonium, spermatocytes, and leydig cells To provide a better representation of the structures, the researchers tabulated the results. Lastly, supplementary analysis of these structures were also done. Results/data: Photo Pituitary Gland Label: acidophil cell, basophil cell, and nucleus of pituicyte The acidophil cells are those which are strongly stained and have more developed outlines. The Basophils have large black spots for their “secretory granules”. The nucleus of the pituicytes are the smaller ones Thyroid gland Label: follicular epithelial cells, colloid The Follicular Epithelial cells are the ones that are surrounding the colloid. Colloid is colored red. Adrenal gland Label: ...
